I doubt it. The OVP causes much different problems with the HFM systems. It could cause the car to stop running, but I can't think of any reason why it would do it repeatedly under rpm conditions.
You need to know what is ceasing when the car cuts out. The simlest start is to read the fault codess. It may lead nowhere. There are many things that self-diagnostics won't cover but real testing is complicated.
